Iodoform gives a precipitate with AgNO ₃ on heating but chloroform does not because

Options

  1. AC - I bond in iodoform is weak and C - Cl bond in chloroform is strong
  2. Bchloroform is covalent
  3. Ciodoform is ionic
  4. DNone of the above

Correct answer

A. C - I bond in iodoform is weak and C - Cl bond in chloroform is strong

Step-by-step solution

On heating C - I bond in CHI ₃ breaks, but C - Cl bond in CHCl ₃ does not break. Thus, AgNO ₃ gives precipitate AgI with iodoform.
